Ok guys, my truck is a 2003 regular cab 2WD Hemi with 3:92 gears and the factory LSD. It has 102k miles on it. I bought it about 7k miles ago. The truck runs strong, but from a dead stop I can't even get it to spin the tires without using the brakes. I have changed the spark plugs, cleaned the throttle body, replaced the air filter, reset the PCM, reset the TPS, and changed the oil. What else can I do to make sure that I have restored any lost HP in the engine?

 

I test drove a 2003 that was just like that before I decided on the 2005 I currently have. No way no how would the 2003 spin on pavement. It also had the LS diff. It seemed to run good but couldn't spin the tires.

My 2005 on the other hand does not have a LS diff and it will spin on command, in fact I find myself squealing the tires on take off all the time completely unintentionally and that is with 3.55 gears. (I desperately want to change the gearing but can't justify the expense)

Sorry, as for restoring the power, a tune up (plugs, wires, TB clean etc) is your best bet unless there are some internal problems. (ie low compression)

 

I don't know of many trucks that can light them from an un braked dig. Mine will barley do it in the rain even with my 4.56's

 

could with my 2004 with 20" dodge rims and 315 50s on it.. Can also sometimes do it with my 35" tires with an empty box on a cooler day.

 

In the rain mine won't keep traction. I was talking about on dry pavement. I was just under the impression from reading other guys posts on here that they were able to smoke them up from a dead stop. Don't guess there's anything wrong with my truck from the responses I've received so far...

 

Ryan,
The torque management is keeping you from lighting up your 03. Do the TMR mod and set her free.

Hey red that link is not working.

 

Superchips!!!!

 

Greg, I have already did the TMR mod. It will do a mean burnout if I powerbrake it to start, but from a dead stop it just hooks up.

 

Hopefully that is going to be my next mod!
